(NOBLESVILLE) - Police have accused a Broad Ripple High School teacher in a child pornography investigation.

Detectives said Robert Fowler, 43, of Noblesville, was arrested Thursday on nine felony counts of possession of child pornography.

The Lafayette Police Department said they received a tip which prompted them to search Fowler's personal computer.

Detectives with the Hamilton County Metro Child Exploitation Task Force said they found images of pre-teen girls and an infant in sexual situations on his computer.

"These were not accidentally possessed or something he just came across on the internet. These were things that were purposefully sent to him and things that he consciously saved and retrieved on different occasions to look at for his sexual gratification," Lt. Cameron Ellison said.

A search of Fowler's computer at Broad Ripple High School revealed no additional evidence, police said.

Fowler was arrested at school and taken to the Hamilton County Jail on a $5,000 bond, shocking students and teachers, RTV6's Tanya Spencer reported.
